An example of a route planning method according to the present embodiment is described next with reference to a flowchart in FIG. 7.

If a disaster such as a severe accident occurs in the plant 1, and an abnormality occurs in the existing device 3 due to the occurrence of the disaster (Step SP1), the route-status-data acquisition unit 81 acquires the route status data (Step SP2).

The route status data includes one or both of damage data indicating a damage status at a specific position in the basic route La and restoration data indicating a restoration status of the damage. The route status data is acquired by using one or both of the mobile terminal 9 and the monitoring camera 23. The route-status-data acquisition unit 81 in the route planning system 10A acquires the route status data indicating the status of the basic route La.

It is determined whether the transportable device 6 (the device vehicle 8) can pass through the basic route La based on the route status data (Step SP3).

Determination whether the transportable device 6 can pass through the basic route La is performed by the determination unit 16. The route status data is displayed on the display device 5 and a worker (manager) can determine whether the transportable device 6 (the device vehicle 8) can pass through the basic route La based on the display result.

At Step SP3, if it is determined that the transportable device 6 can pass through the basic route La (YES at Step SP3), the basic route data indicating the basic route La is displayed on the display device 5 (Step SP4). The route status data can be displayed on the display device 5. The route status data can be output as audio data from the audio output device 5S. For example, audio data of a site report of a worker can be output. For example, when at least one of facts that there is no damage in the basic route La, that the damage having occurred in the basic route La is minor, and that restoration of the damage having occurred in the basic route La has been complete is recognized, it is determined that the transportable device 6 can pass through the basic route La.

FIG. 8 is a diagram illustrating an example of the display device 5 that displays the basic route data. As illustrated in FIG. 8, the display device 5 displays the basic route data indicating the basic route La, together with map data of the plant 1.

As illustrated in FIG. 8, in the present embodiment, the transportable device 6 (the device vehicle 8) is provided in plural in the plant 1. The transportable devices 6 are respectively placed (held) at different standby positions PJ1. The route planning system 10A allocates an optimum transportable device 6 from the plurality of transportable devices 6, based on the type of the existing device 3 having an abnormality and the position of the existing device 3 having an abnormality. The route planning system 10A outputs the basic route data so as to connect the standby position PJ1 at which the allocated transportable device 6 is placed to the optimum predetermined position PJ2 for substitute for the existing device 3 having an abnormality.

The basic route data and the route status data are transmitted from the computer system 4 to the mobile terminal 9 held by a worker who drives the allocated device vehicle 8. The basic route data and the route status data are transmitted wirelessly to the mobile terminal 9 mounted on the device vehicle 8. The worker receives an instruction to move the transportable device 6 to the predetermined position PJ2 via the mobile terminal 9. The worker can drive the device vehicle 8 so that the transportable device 6 is carried to the predetermined position PJ2 passing through the basic route La, while watching the basic route data displayed on the display unit of the mobile terminal 9.

At Step SP3, if it is determined that the transportable device 6 cannot pass through the basic route La (NO at Step SP3), the route status data is displayed on the display device 5 together with the basic route data indicating the basic route La by the display control unit 18 (Step SP5). For example, when it is recognized that damage such as a landslide has occurred at a specific position in the basic route La, it is determined that the transportable device 6 cannot pass through the basic route La. The route status data can be output as audio data from the audio output device 5S. For example, audio data of a site report (a damage status report) of the worker who holds the mobile terminal 9 and has confirmed the route can be output.

FIG. 9 is a diagram illustrating an example of the display device 5 that displays the basic route data. As illustrated in FIG. 9, the display device 5 displays the basic route data indicating the basic route La and the route status data, together with the map data of the plant 1.

As described above, the route status data includes the image data. As illustrated in FIG. 9, a mark (as an example, a cross (x)) is displayed at a specific position in the basic route La where damage has occurred. Data of the damage having occurred at the specific position is displayed as image data in association with the specific position. Further, the contents of the damage (in this example, a landslide) are displayed on the display device 5. By touching an icon displayed on the display unit of the display device 5, audio data of the site report of a worker can be output.

The estimation unit 14 calculates an expected restoration time (an expected restoration time point) required for restoring the specific position. As described above, the estimation unit 14 can calculate the expected restoration time (or the expected restoration time point) required for restoring the specific position in the basic route La, based on the log data in the past stored in the storage unit 15 and the damage data indicating the damage status at the specific position in the basic route La acquired by the data acquisition unit 80. The calculated expected restoration time (or the expected restoration time point) is displayed on the display device 5.

The area-status-data acquisition unit 82 acquires the area status data (Step SP6). The area status data indicates a status of the area in which the transportable device 6 is installed for substitution.

Even if it is determined that the basic route La is impassable, the route status data and the area status data can be transmitted from the computer system 4 to the mobile terminal 9 held by a worker who drives the allocated device vehicle 8. The route status data is wirelessly transmitted to the mobile terminal 9 mounted on the device vehicle 8. The worker can ascertain the route status and the area status via the mobile terminal 9.

FIG. 10 is a diagram schematically illustrating an example of an area 600 around the existing device (the existing power source 3B) having an abnormality. The existing device 3 supplies power to an electric device 300 of the plant 1 via a relay device 50 including a connector. If an abnormality occurs in the existing device 3, the transportable device 6 (the transportable power source 6B) is installed in the area 600 and connected to the relay device 50.

When the transportable device 6 enters the area 600 for substitution for the existing device 3 and approaches the relay device 50, the transportable device 6 can approach the relay device 50 via a plurality of routes. In the example illustrated in FIG. 10, the transportable device 6 can approach the relay device 50 through at least one of a first route Lb1 and a second route Lb2.

An obstacle such as debris may be present inside the area 600 due to occurrence of a disaster. If the obstacle is located in the second route Lb2, the transportable device 6 needs to approach the relay device 50 by passing through the first route Lb1.

In the present embodiment, the area status data indicating the status of the area 600 is acquired by the interface unit 11. The area status data includes one or both of damage data indicating a damage status of the area 600 and restoration data indicating a restoration status of the damage. The area status data is acquired by using one or both of the mobile terminal 9 and the monitoring camera 23. The interface unit 11 of the route planning system 10A acquires the route status data indicating the status of the area 600.

The generation unit 13 decides the predetermined position PJ2 at which the transportable device 6 is installed based on the area status data (Step SP7). In the example illustrated in FIG. 10, an end point of the first route Lb1 is decided as the predetermined position PJ2.

Priority data indicating a parameter having a priority in generation of the alternative route data is input from the input device 20 and acquired by the priority-data acquisition unit 84 (Step SP8). The priority data acquired by the priority-data acquisition unit 84 is supplied to the generation unit 13. The generation unit 13 generates the alternative route data based on the priority data (Step SP9).

The parameter having a priority in generation of the alternative route data includes at least one of a moving time required for the transportable device 6 to arrive at the predetermined position PJ2, a moving distance of the transportable device 6 to the predetermined position PJ2, a gradient of a road surface on which the transportable device 6 travels until arriving at the predetermined position PJ2, a curvature of the road surface on which the transportable device 6 travels until arriving at the predetermined position PJ2, and a width of the road surface on which the transportable device 6 travels until arriving at the predetermined position PJ2. The priority data indicating these parameters is input via the input device 20.

For example, when it is desired that the transportable device 6 arrives at the predetermined position PJ2 in a short time, the “moving time” is input as the priority data. When it is desired to suppress a traveling distance of the transportable device 6, the “moving distance” is input as the priority data. When it is desired to carry the transportable device 6 without tilting the transportable device 6, the “gradient of the road surface” or the “curvature of the road surface” is input as the priority data. When the transportable device 6 or the vehicle 7 that transports the transportable device 6 is large, the “width of the road surface” is input as the priority data.

As described above, the data of the track in the plant 1 on which the device vehicle 8 can travel is stored in the storage unit 15. The generation unit 13 extracts an optimum track from tracks provided in the plant 1 to generate the alternative route Lb based on the track data.

After the alternative route data has been generated, the estimation unit 14 estimates one or both of the moving time required for the transportable device 6 passing through the alternative route Lb to arrive at the predetermined position PJ2 and the moving distance thereof (Step SP10).

After the alternative route data has been generated, the display control unit 18 causes the display device 5 to display the alternative route data indicating the alternative route Lb (Step SP11).

FIG. 11 is a diagram illustrating an example of the display device 5 that displays the alternative route data. As illustrated in FIG. 11, the display control unit 18 causes the display device 5 to display the alternative route data indicating the alternative route Lb, together with the map data of the plant 1. The audio output device 5S can output the alternative route data by voice.

Further, the display control unit 18 causes the display device 5 to display the moving time data indicating the moving time (expected amount of time required) of the transportable device 6 passing through the alternative route Lb, which has been estimated by the estimation unit 14. The display control unit 18 can cause the display device 5 to display the moving distance data indicating the moving distance (expected moving distance) of the transportable device 6 passing through the alternative route Lb, which has been estimated by the estimation unit 14.

The alternative route data and the route status data are transmitted from the computer system 4 to the mobile terminal 9 held by a worker who drives the allocated device vehicle 8. The worker receives an instruction to move the transportable device 6 to the predetermined position PJ2 via the mobile terminal 9. The worker can drive the device vehicle 8 so that the transportable device 6 is carried to the predetermined position PJ2 through the alternative route Lb, while watching the alternative route data displayed on the display device 9C of the mobile terminal 9.

FIG. 12 is a diagram illustrating an example of the display device 5 that displays the position data of the transportable device 6 moving on the alternative route Lb. As illustrated in FIG. 12, the display device 5 can display the position data of the transportable device 6 moving on the alternative route Lb, together with the map data of the plant 1 and the alternative route data. In the example illustrated in FIG. 12, the position data of the transportable device 6 is displayed by using a circular icon 40.

In the present embodiment, the estimation unit 14 calculates the expected restoration time required for restoring the specific position in the basic route La, and can estimate the moving time required for the transportable device 6 passing through the basic route La to arrive at the predetermined position PJ2, taking the expected restoration time into consideration. When the moving time of the transportable device 6 when passing through the basic route La is compared with the moving time of the transportable device 6 when passing through the alternative route Lb, and it is determined that the expected arrival time to the predetermined position PJ2 when passing through the basic route La is earlier than that when passing through the alternative route Lb, the transportable device 6 does not necessarily need to pass through the alternative route Lb.

In the present embodiment, the route status data is wirelessly transmitted to the mobile terminal 9 held by a worker who drives the device vehicle 8 allocated to move to the predetermined position PJ2. The route status data can be wirelessly transmitted also to the mobile terminal 9 held by a worker who drives the device vehicle 8 that is not allocated to move to the predetermined position PJ2. The route status data can be wirelessly transmitted to the mobile terminal 9 held by a worker who does not drive the device vehicle 8. Accordingly, all the workers can ascertain the route status.

As described above, according to the present embodiment, when it is determined that it is difficult to transport the transportable device 6 quickly to the predetermined position PJ2 based on the route status data of the basic route La, the alternative route data is generated. Therefore, route planning of the transportable device 6 is appropriately performed based on the alternative route data displayed on the display device 5. For example, a worker (manager) can perform the route planning appropriately by using the alternative route data displayed on the display device 5.

According to the present embodiment, the area status data indicating the status of the area 600 in which the transportable device 6 is installed for substitution for the existing device 3 is acquired. The predetermined position PJ2 is decided based on the acquired area status data and the alternative route data is generated. Accordingly, even if the area 600 is changed to be in an abnormal status different from the normal time such that there is an obstruction in the area 600 because of a disaster, the route planning of the transportable device 6 is appropriately performed based on the area status data.

According to the present embodiment, the route status data includes one or both of the damage data indicating the damage status at a specific position in the basic route La and the restoration data indicating the restoration status of the damage. Accordingly, when the basic route La is damaged, the route planning of the transportable device 6 is appropriately performed based on the alternative route data. When the basic route La is restored, the route planning of the transportable device 6 is appropriately performed based on at least one of the basic route data and the alternative route data.

According to the present embodiment, it is determined whether the transportable device 6 can pass through a specific position in the basic route La where damage has occurred based on the route status data including the damage data. When it is determined that the transportable device 6 cannot pass through the specific position in the basic route La, the alternative route data is generated. Accordingly, the route planning of the transportable device 6 is appropriately performed according to the status of the specific position where the damage has occurred in the basic route La.

According to the present embodiment, one or both of the moving time required for the transportable device 6 passing through the alternative route Lb to arrive at the predetermined position PJ2 and the moving distance thereof is estimated. Accordingly, the route planning of the transportable device 6 is appropriately performed based on one or both of the estimated moving time and moving distance.

According to the present embodiment, the route status data includes the damage data indicating the damage status of the specific position in the basic route La. The moving time required for the transportable device 6 passing through the basic route La to arrive at the predetermined position PJ2 is estimated, taking into consideration the expected restoration time required for restoring the specific position in the basic route La. Accordingly, the expected moving time when the transportable device 6 passes through the basic route La can be compared with the expected moving time when the transportable device 6 passes through the alternative route Lb based on the expected restoration time of the specific position in the basic route La. The route planning of the transportable device 6 is appropriately performed based on a comparison result.

According to the present embodiment, the display device 5 displays one or both of the moving time data indicating the estimated moving time of the transportable device 6 and the moving distance data indicating the estimated moving distance. Accordingly, the route planning of the transportable device 6 is appropriately performed based on one or both of the moving time data and the moving distance data displayed on the display device 5.

According to the present embodiment, the alternative route data generated by the generation unit 13 is held in the database unit 19. Accordingly, the alternative route data is accumulated. The accumulated alternative route data contributes to appropriate execution of the route planning in case of future emergency.

According to the present embodiment, the position data indicating the position of the transportable device 6 is also displayed on the display device 5. Accordingly, the position of the transportable device 6 is recognized on a real-time basis via the display device 5.

A third embodiment is described. In the following descriptions, constituent elements like or equivalent to those in the above embodiments are denoted by like reference signs and descriptions thereof will be simplified or omitted.

If a natural phenomenon such as an earthquake, a typhoon, or a tsunami has occurred, for example, in a state in which the transportable device 6 is held at the standby position PJ1, there may be damage such that the transportable device 6 moves from the standby position PJ1 or the position detection device 22 mounted on the transportable device 6 has a failure. If such damage has occurred, in the present embodiment, a confirmation work of the state of the transportable device 6 is performed. The confirmation work can be performed by visual judgment by a worker who has moved to the standby position PJ1, or via aerial images taken by a drone that has flown in the air to the standby position PJ1.

According to the present embodiment, the display control unit 18 causes the display device 5 to display a transportable device 6 determined not to have been damaged, and a transportable device 6 determined to have been damaged or a transportable device 6 that is unclear if it has been damaged, by the confirmation work in different display modes from each other. The transportable device 6 that is unclear if it has been damaged includes a transportable device 6 for which the confirmation work has not be performed.

FIG. 14 is a flowchart illustrating an example of an operation of the route planning system 10A according to the present embodiment. FIGS. 15, 16, and 17 illustrate a display example of the display device 5 according to the present embodiment.

When the transportable device 6 held at the standby position PJ1 is normal, as illustrated in FIG. 15, the display control unit 18 causes the display device 5 to display the transportable device 6 in a first display mode. In the present embodiment, it is assumed that a white icon Ca indicating the transportable device 6 is displayed on the display device 5.

If a natural phenomenon such as an earthquake, a typhoon, or a tsunami has occurred in the state in which the transportable device 6 is held at the standby position PJ1, as illustrated in FIG. 16, the display control unit 18 causes the display device 5 to display all the transportable devices 6 in a second display mode, which is different from the first display mode (Step SR1). In the present embodiment, it is assumed that a red icon Cb indicating the transportable device 6 is displayed on the display device 5.

The confirmation work of the state of the transportable device 6 is performed. For example, when a worker moves to the standby position PJ1 to perform the confirmation work, it is confirmed whether the transportable device 6 has moved from the standby position PJ1 and whether the transportable device 6 has a failure.

The worker operates the mobile terminal 9 to transmit a confirmation result to the route planning system 10A. The data acquisition unit 80 acquires confirmation data indicating the state of the transportable device 6, transmitted from the mobile terminal 9 (Step SR2).

In the present embodiment, the confirmation data includes first confirmation data indicating that the transportable device 6 is present at the standby position PJ1 and does not have a failure, second confirmation data indicating that the transportable device 6 has moved from the standby position PJ1 but does not have a failure, third confirmation data indicating that the transportable device 6 is present at the standby position PJ1 but has a failure, fourth confirmation data indicating that the transportable device 6 has moved from the standby position PJ1 and has a failure, and fifth confirmation data indicating that it is unclear whether the transportable device 6 has been damaged.

As illustrated in FIG. 17, the display control unit 18 causes the display device 5 to display the transportable device 6, to which the first confirmation data has been transmitted, in the first display mode. On the other hand, the display control unit 18 causes the display device 5 to display the transportable device 6, to which the second, third, fourth, or fifth confirmation data has been transmitted, in the second display mode (Step SR3).

In this manner, according to the present embodiment, the transportable device 6 determined by the confirmation work that it has not been damaged is displayed by the white icon Ca, and the transportable device 6 determined to have been damaged or the transportable device 6 that is unclear if it has been damaged is displayed by the red icon Cb.

The transportable device 6 displayed by the white icon Ca is a transportable device 6 determined not to have been damaged as a result of the confirmation work. The transportable device 6 displayed by the red icon Cb is a transportable device 6 determined to have been damaged as a result of the confirmation work or a transportable device 6 in an unconfirmed state, for which the confirmation work has not been performed. A worker (manager) can judge which transportable device 6 is trustable and which transportable device 6 is not trustable, by watching the display device 5.

In the present embodiment, it is assumed that after a natural phenomenon such as an earthquake, a typhoon, or a tsunami has occurred, the confirmation work is performed, and a confirmed transportable device 6, a damaged transportable device 6, and an unconfirmed transportable device 6, among the plurality of transportable devices 6, are displayed respectively in different display modes based on a result of the confirmation work. For example, if there is a communication abnormality in the position detection device 22 of a part of the transportable devices 6, the display control unit 18 can cause the display device 5 to display the transportable device 6 having a communication abnormality and the transportable device 6 having no communication abnormality respectively in different display modes.

Further, after the natural phenomenon such as an earthquake, a typhoon, or a tsunami has occurred, the confirmation work can be performed with respect to a plurality of routes in the plant 1. Based on a result of the confirmation work, the display control unit 18 can cause the display device 5 to display a passable route, a damaged route, and an unconfirmed route, among the plurality of routes, respectively in different display modes. A worker (manager) can judge which route is to be used and which route is not to be used, by watching the display device 5.

In the case where a plurality of detection devices that detect a quantity of state (for example, water level sensors) are provided in the plant 1, and of the plurality of detection devices, there is a detection device that does not transmit a detection signal to the communication device 21 of the route planning system 10A, the display control unit 18 can cause the display device 5 to display an icon of an abnormal detection device that does not transmit a detection signal and an icon of a normal detection device in different display modes. A worker (manager) can judge which detection device is to be used and which detection device is not to be used by watching the display device 5.

The display control unit 18 causes the display device 5 to display the position data and the item data 44 in association with each other. Accordingly, it can be quickly recognized which transport vehicle 30 is transporting articles, and what articles and how many articles the transport vehicle 30 is transporting. Further, it can be quickly recognized which transport vehicle 30 is currently located where and when it will arrive.

Further, the display control unit 18 causes the display device 5 to display the planned route data of the transport means 30, the position data, and the item data 44 in association with each other. Accordingly, it can be quickly recognized on which route the transport means 30 is traveling to arrive at a destination. At this time, a route change can be studied based on the traffic data.

The display control unit 18 causes the display device 5 to display the position data of the transport means 30 on a real-time basis. The display control unit 18 sequentially updates the position data of the transport means 30 to the latest position data and causes the display device 5 to display the latest position data of the transport means 30. Further, the display control unit 18 causes the display device 5 to display update time data 43 indicating the update time at which the position data of the transport means 30 has been updated.

The determination unit 16 determines, for example, whether the drinking water to be supplied from the first supplier to the plant 1 arrives at an expected time. When it is determined that the drinking water will not arrive at the expected time, the instruction unit 130 outputs an instruction signal so that the drinking water will be supplied from the second supplier. A manager watching the display device 5 illustrated in FIG. 22 can instruct a change from the first supplier to the second supplier. Accordingly, the plant 1 can obtain the drinking water quickly.

As described above, according to the present embodiment, the display control unit 18 causes the display device 5 to display the article data in association with the arrangement status data. Accordingly, the manager of the plant 1 can perform planning to quickly arrange necessary and sufficient articles based on the display result on the display device 5.

According to the present embodiment, the arrangement status data includes not only the target amount data indicating the target amount of the articles and the expected arrival time data indicating the expected time of arrival of the articles to the plant 1, but also the position data indicating the position of the transport vehicle 30 that transports the articles to the plant 1. Accordingly, planning to arrange the necessary and sufficient articles quickly can be performed based on the display result including the position data on the display device 5.

Further, according to the present embodiment, if it is determined that the articles from the first supplier will not arrive at the expected time, it is arranged that specific articles will be supplied from the second supplier. Accordingly, necessary articles can be obtained quickly.

Further, when it is determined that the articles from the supply source will not arrive at the expected time, or when the secured amount of the arranged articles is not sufficient with respect to the target amount, separate arrangement can be performed.

Eighth Embodiment

An eighth embodiment is described. In the following descriptions, constituent elements like or equivalent to those in the above embodiments are denoted by like reference signs and descriptions thereof will be simplified or omitted.

In the above embodiments, it is assumed that the decision-making support system 100 including the route planning system 10A is applied to plant facilities. The route planning system 10A can be applied not only to plant facilities, but also to various applicable targets, for example, traffic facilities such as motorways or railways, or building facilities such as condominium buildings or commercial facilities.

An example in which the route planning system 10A is applied to traffic facilities including motorways is described below.

If an abnormality occurs in an existing facility of the traffic facilities, the route planning system 10A plans a route for moving a support facility from the standby position PJ1 to the predetermined position PJ2 for support in order to support the existing facility by the support facility.

Motorways, traffic lights, and guardrails are exemplified as the existing facility in the traffic facilities. A collapse on a road surface of a motorway, an accident on a motorway, a failure of traffic lights, and a breakage of guardrails are exemplified as the abnormality of the existing facility in the traffic facilities.

The support facility includes various facilities that can handle an abnormality in the existing facility. The support facility is a movable body. For example, as the support facility when the road surface of the motorway has collapsed, a transport vehicle that transports a construction machine to repair the motorway and materials (gravels, an asphalt material, and the like) to repair the collapse is exemplified. As the support facility when an accident occurs on the motorway, ambulances, fire engines, police cars, maintenance service vehicles, tow trucks, crane trucks, helicopter ambulances, vehicles for the Japan Self-Defense forces, buses, food transport vehicles, and fuel transport vehicles are exemplified. As the support facility when the traffic lights are broken, police cars, high-place service vehicles, self-propelled signature cars, and transportable traffic lights are exemplified. As the support facility when the guardrail is broken, construction vehicles to repair the guardrail, police cars, and self-propelled signature cars are exemplified.

In the present embodiment, an example of planning a route for the support facility at the time of occurrence of an accident on a motorway is described. An example in which the support facility is a support vehicle 6H that can handle an accident is described. In the present embodiment, the support vehicle 6H includes a maintenance service vehicle (a vehicle of Type: A), a tow truck (a vehicle of Type: B), and a crane truck (a vehicle of Type: C). The maintenance service vehicle is a service vehicle that transports workers who work at an accident site, or performs site maintenance activity so that a secondary damage does not occur at the accident site.

The support vehicle 6H stands by at the standby position PJ1. As the standby position PJ1, for example, a car park of a motorway management company provided near an interchange of a motorway is exemplified. The predetermined position PJ2 is an accident site. The basic route La for moving the support vehicle 6H from the standby position PJ1 to the predetermined position PJ2 is decided in advance.

For example, there is a possibility that the support vehicle 6H is not able to pass through the basic route La due to occurrence of a traffic congestion or a disaster. If such a status that the support vehicle 6H cannot pass through the basic route La occurs, the route planning system 10A plans the alternative route Lb for moving the support vehicle 6H to the predetermined position PJ2.

As described above with reference to FIG. 6, the data acquisition unit 80 includes the route-status-data acquisition unit 81, the area-status-data acquisition unit 82, the position-data acquisition unit 83, and the priority-data acquisition unit 84.

The route-status-data acquisition unit 81 acquires the route status data indicating the status of the basic route La. The route status data includes at least one of traffic congestion data indicating a traffic congestion status of the basic route La, damage data indicating a damage status at a specific position in the basic route La, and restoration data indicating a restoration status of the damage. The traffic congestion data can be acquired from an existing Vehicle Information and Communication System. SNS (Social Networking Service) data indicating a status of the basic route La transmitted from the general public by using the SNS can be acquired by the route-status-data acquisition unit 81.

The area-status-data acquisition unit 82 acquires the area status data indicating the status of the area of the accident site being the predetermined position PJ2. For example, a worker of a motorway management company happened to be at the site of an accident can transmit the area status data to the area-status-data acquisition unit 82 by using the mobile phone. The SNS data indicating the status of the area of the accident site transmitted from a person happened to be at the site of an accident can be acquired by the area-status-data acquisition unit 82. If a monitoring camera is provided on the motorway, image data acquired by the monitoring camera that has captured the image of the accident site can be acquired by the area-status-data acquisition unit 82.

The position-data acquisition unit 83 acquires position data indicating the position of the support vehicle 6H.

The generation unit 13 generates alternative route data indicating the alternative route Lb for moving the support vehicle 6H to the predetermined position PJ2 based on the route status data acquired by the route-status-data acquisition unit 81.

The estimation unit 14 estimates one or both of the moving time required for the support vehicle 6H passing through the alternative route Lb generated by the generation unit 13 to arrive at the predetermined position PJ2 and the moving time thereof.

The storage unit 15 stores therein data required for planning of the route of the support vehicle 6H. The storage unit 15 stores therein the track data indicating the road on which the support vehicle 6H travels and the basic route data indicating the basic route La.

The basic route data or the alternative route data is output to a mobile terminal held by a worker who drives the support vehicle 6H. The worker of the support vehicle 6H drives the support facility from the standby position PJ1 to the predetermined position PJ2 while watching the basic route data or the alternative route data displayed on the display device of the mobile terminal.

An example of a route planning method according to the present embodiment is described next. If an accident occurs on a motorway, the route-status-data acquisition unit 81 acquires the route status data. The determination unit 16 or the manager determines whether the support vehicle 6H can pass through the basic route La based on the route status data.

If it is determined that the support vehicle 6H can pass through the basic route La, the basic route data indicating the basic route La is displayed on the display device 5. FIG. 26 is a diagram illustrating an example of the display device 5 that displays the basic route data. As illustrated in FIG. 26, the display device 5 displays the basic route data indicating the basic route La together with map data of the vicinity of the accident site.

A car park of a motorway management company, which is the standby position PJ1, is present in a plurality of places. As illustrated in FIG. 26, in the present embodiment, a list of the plurality of standby positions PJ1 near the accident site and the support vehicles 6H standing by at the respective standby positions PJ1 is displayed. In an example illustrated in FIG. 26, the display control unit 18 causes the display device 5 to display the display data indicating that two maintenance service vehicles (Type: A) are standing by in “Area 1” indicating a first standby position PJ1, one maintenance service vehicle (Type: A) and one tow truck (Type: B) are standing by in “Area 2” indicating a second standby position PJ1, one maintenance service vehicle (Type: A) is standing by in “Area 3” indicating a third standby position PJ1, three maintenance service vehicles (Type: A) are standing by in “Area 4” indicating a fourth standby position PJ1, and one maintenance service vehicle (Type: A) and one crane truck (Type: C) are standing by in “Area 5” indicating a fifth standby position PJ1.

The route planning system 10A allocates the most appropriate support vehicle 6H from the support vehicles 6H based on the status of the accident site. The route planning system 10A outputs the basic route data so as to connect the standby positions PJ1 where the allocated support vehicles 6H are standing by and the predetermined position PJ2 indicating the accident site to each other.

The basic route data and the route status data are transmitted from the computer system 4 to the mobile terminals held by the workers who drive the allocated support vehicles 6H. The basic route data and the route status data are transmitted wirelessly to the mobile terminals mounted on the support vehicles 6H. The worker receives an instruction to move the support vehicle 6H to the predetermined position PJ2 via the mobile terminal. The worker can drive the support vehicle 6H so that the support vehicle 6H is carried to the predetermined position PJ2 passing through the basic route La, while watching the basic route data displayed on a display unit of the mobile terminal.

If it is determined that the support vehicle 6H cannot pass through the basic route La, the generation unit 13 generates the alternative route data. After the alternative route data has been generated, the display control unit 18 causes the display device 5 to display the alternative route data indicating the alternative route Lb. The display control unit 18 causes the display device 5 to display the alternative route data indicating the alternative route Lb together with the map data of the vicinity of the accident site.

The alternative route data and the route status data are transmitted from the computer system 4 to the mobile terminal held by the worker who drives the allocated support vehicle 6H. The worker receives an instruction to move the support vehicle 6H to the predetermined position PJ2 via the mobile terminal. The worker can drive the support vehicle 6H so that the support vehicle 6H is carried to the predetermined position PJ2 passing through the alternative route La, while watching the alternative route data displayed on the display unit of the mobile terminal.

As described above, according to the present embodiment, if it is determined that it is difficult to move the support vehicle 6H quickly to the predetermined position PJ2 based on the route status data of the basic route La, the alternative route data is generated. Accordingly, route planning of the support vehicle 6H is appropriately performed based on the alternative route data displayed on the display device 5.

Ninth Embodiment

A ninth embodiment is described. In the following descriptions, constituent elements like or equivalent to those in the above embodiments are denoted by like reference signs and descriptions thereof will be simplified or omitted.

In the above embodiments, it is assumed that the decision-making support system 100 including the article-arrangement planning system 10B is applied to plant facilities. The article-arrangement planning system 10B can be applied not only to plant facilities, but also to various applicable targets, for example, traffic facilities such as motorways or railways, or building facilities such as condominium buildings or commercial facilities.

An example in which the article-arrangement planning system 10B is applied to the traffic facilities including motorways is described below.

If an abnormality occurs on, for example, a motorway, the article-arrangement planning system 10B acquires the arrangement status data indicating the arrangement status of articles to be arranged to respond to the abnormality. The display control unit 18 causes the display device 5 to display the arrangement status data.

A collapse on a road surface of a motorway, accumulation of snow on the motorway, an accident on the motorway, and the like are exemplified as the abnormality on the motorway.

Articles to be arranged to respond to the abnormality on the motorway includes at least one of transportable articles and movable emergency vehicles. For example, as the articles when the road surface of the motorway has collapsed, a construction machine that repairs the motorway, and materials (gravels, an asphalt material, and the like) to repair the collapse are exemplified. As the articles at the time of accumulation of snow on the motorway, an antifreezing agent, a snow-plow truck, vehicles of the Japan Self-Defense Forces, and the like are exemplified. As the articles at the time of occurrence of an accident on the motorway, medical devices, first aid devices, medicines, clothes, blankets, a tow truck, a crane truck, and the like are exemplified.

An example in which the arrangement status data of articles to be arranged at the time of occurrence of an accident due to accumulation of snow on the motorway is acquired is described in the present embodiment.

As described above with reference to FIG. 19, the article-arrangement planning system 10B includes the arrangement-status-data acquisition unit 85. The arrangement status data includes at least one of the target amount data indicating a target amount of articles, the expected arrival time data indicating an expected time of arrival of the articles to the accident site, the actual amount data indicating a secured amount of arranged articles, and the position data indicating the position of the transport vehicle that transports the articles to the accident site.

In the following descriptions, it is assumed that the computer system 4 in the article-arrangement planning system 10B is mounted on an emergency vehicle that has arrived at the site of the accident.

If an accident occurs due to accumulation of snow on the motorway and articles for responding to the accident are required, request data is output to external facilities from the computer system 4, for example, mounted on an emergency vehicle having arrived at the site of the accident. The request data includes the article data indicating articles required in the site of the accident, the target amount data indicating a target amount of the articles, and the desired arrival time data indicating the desired arrival time of the articles.

Transport of articles is started. The arrangement-status-data acquisition unit 85 acquires arrangement status data indicating each arrangement status of the plurality of articles. The display control unit 18 causes the display device 5 mounted on an emergency vehicle to display the article data indicating the articles.

FIG. 27 is a diagram illustrating an example of the display device 5 according to the present embodiment. As illustrated in FIG. 27, the display control unit 18 causes the display device 5 to display item data 44 in which the article data is displayed in association with the arrangement status data. The item data 44 includes article data (an antifreezing agent and the like), actual amount data (a secured amount), target amount data (a target amount), expected arrival time data (an expected arrival time), and affiliation data (affiliation). The item data 44 also includes traffic data indicating the status of the transport route of the transport means 30, and planned route data indicating the planned route of the transport means 30.

The arrangement status data includes the position data indicating the positions of the support vehicles. In the present embodiment, the position data of the support vehicles is illustrated by icons 41. FIG. 27 illustrates an example in which four support vehicles (articles) including a transport vehicle that transports an antifreezing agent, a crane truck, a tow truck, and a snow-plow truck are travelling toward a site 1H of the accident.

The display control unit 18 causes the display device 5 to display the position data and the item data 44 in association with each other. Accordingly, it can be quickly recognized which support vehicle is transporting articles, and what articles and how many articles the support vehicle is transporting. Further, it can be quickly recognized which support vehicle is currently located where and when it will arrive at the site.

The display control unit 18 causes the display device 5 to display the position data of the support vehicle on a real-time basis. The display control unit 18 sequentially updates the position data of the support vehicle to the latest position data and causes the display device 5 to display the latest position data of the support vehicle. Further, the display control unit 18 causes the display device 5 to display update time data 43 indicating the update time at which the position data of the support vehicle has been updated.

As described above, according to the present embodiment, the display control unit 18 causes the display device 5 to display the article data in association with the arrangement status data. Therefore, a worker of an emergency vehicle that has arrived at the site of an accident can perform planning for quickly arranging necessary and sufficient articles based on the display result on the display device 5.

The abnormal condition data satisfying the priority display standard as described in the eighth embodiment includes facility data having been changed at a change rate exceeding the reference value set in advance in, for example, traffic facilities or oil/gas facilities.
